Yep, just another broken promise.

As recently as last week, when asked at a White House press briefing about the president's first term promise to close Guantanamo Bay, Jay Carney reiterated the president's promise: "As you know, the president remains committed to that.  He agrees with military leaders as well as his immediate predecessor that we ought to do that. There are obviously obstacles in Congress to that, but we will continue to work towards that goal because he believes it's in the best interests of our national security."
